[Stone burden on extracorporeal shock wave lithotripsy].
Based on the 89 stones treated by ESWL therapy alone, the factors which influence the number of ESWL shots were analyzed. Stone volume was calculated by summing up the value "length x short axis" for each stone. The value correlated well with the number of shots needed to disintegrate the stone (p less than 0.01). The stones below the pelvis-ureteral junction needed twice shots compared with st...
متن کاملThe use of resonant scattering to identify stone fracture in shock wave lithotripsy.
There is currently little feedback as to whether kidney stones have fractured during shock wave lithotripsy. Resonant scattering of the lithotripter shock wave was used here to differentiate intact and fractured stone models in water. Scattering, including reflection and radiation due to reverberation from within the stone, was calculated numerically with linear elasticity theory and agreed wel...
متن کاملElastic interface waves along a fracture
Non-welded interfaces can be treated as a displacement discontinuity characterized by elastic stiffnesses. Applying this boundary condition to a generalized Rayleigh wave, it is shown that a fast and a slow dispersive wave can propagate along the fracture, even when the seismic properties of the rock on each side are identical.

abstract this quasi-experimental study was aimed at examining the impact of storyline complexity on the grammatical accuracy and complexity of advanced and intermediate efl learners. a total of 65 advanced and intermediate efl learners were selected from iran language institute (ili). an intact group including 35 intermediate participants and another intact group with 30 advanced participants ...
an investigation into iranian teachers consistency and bias in evaluation of students writings
while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
